- MaxLight™550 is a new Yellow-Green photostable dye conjugate comparable to Alexa Fluor™546, 555, DyLight™549 , Cy3™, TRITC and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (550nm); Emission (575nm); Extinction Coefficient 150,000. A glycoprotein (256 amino acids) of 30kD, which exists as both a monomer and a 55kD dimer on the surface of activated T cells is identified as 4-1BB (also known as CD137). 4-1BB is an inducible receptor-like protein expressed on the cell surface of activated splenic T cells and thymocytes. 4-1BB is structurally related to the members of NGFR/TNFR superfamily which are characterized by the presence of three-six patterns of a cysteine-rich motif in their extracellular domains. Other members of this family include low affinity NGFR, two receptors for TNF (TNFR-I & TNFR-II), CD30, CD40, OX40, Fas, and CD27. These molecules are involved in cell growth, survival, and death processes. The cytoplasmic domain of 4-1BB include two runs of acidic amino acids, a potential p56lck binding site, five consecutive glycines at the C-terminus, and four potential phosphorylation sites: one tyrosine, two threonine, and one serine. The cytoplasmic domain of 4–1BB displays sequence homology to CD4 and CD8 and is responsible for the binding of 4–1BB to p56lck, a protein tyrosine kinase involved in T cell proliferation. Applications: Flow Cytometry: 1:10-1:50. Use 10ul of the suggested working dilution to label 10e6 cells in 100ul. Optimal working dilutions to be determined by researcher. Recommended Secondary Antibody: F(ab')2 Goat anti-rat IgG: RPE (mouse adsorbed) Recommended Negative Controls: Rat IgG2a Negative Control Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™550 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
